Yankees fans thought they were giving a Bronx jeer to a cutout of former Yankee Robinson Cano. But the joke was on them, when Cano, who made his debut with the Seattle Mariners this season, jumped out from behind the cardboard.

The stunned hecklers quickly changed their tune with the second baseman standing before them — part of a stunt that aired on Monday night’s “The Tonight Show Starring Jimmy Fallon.”
